应用HD-FLOW 技术在11-13+6 周筛查帆状脐带胎盘入口的 准确性
Zhongshan Daxue xuebao. Yixue kexue ban, 2017 摘要：【目的】探讨超声早孕期筛查帆状脐带胎盘入口的可行性。【方法】收集大连市妇女儿童医疗中心行早孕筛 查、中孕系统筛查且在我院分娩的孕妇2 796 例，胎儿2998 个。早孕期（11~13+6 周）筛查脐带胎盘入口位置，将检查结果 分成三组，Ⅰ组为：明确显示脐带胎盘入口位于与胎膜上，沿着胎膜走行一段距离后，再进入胎盘，该组诊断为帆状胎盘。 Ⅱ组为：脐带胎盘入口位于胎盘边缘，无法区分插入点位于胎盘实质及胎膜上。Ⅲ组为：组明确显示脐带胎盘入口处为胎 盘实质，该组诊断为正常胎盘。将每组结果与中孕期 ...

Study of the relationship between physiological process of placental separation and postpartum hemorrhage by ultrasound [PDF]
, 2013 目的：应用超声技术研究胎盘剥离生理过程，探讨胎盘剥离机制，分析第三产程子宫腔内部胎盘剥离过程与产后出血的关系，期望将超声诊断应用领域扩大到预测产后出血方面。进而有依据的早期干预产后出血，减少产后出血发生，降低产妇死亡率。 方法：选择2012年3月1日~2013年2月28日期间，在我院产房夜间自然分娩、单胎头位、产程进展顺利、无并发症和合并症的初产妇66例，使用B超诊断仪对该66例产妇胎盘剥离过程进行动态监测，记录分娩前后胎盘位置情况、子宫收缩情况、胎盘剥离情况等信息，准确记录第三产程和各分期时间 ...
